McTofu Could Be Next: Gary Hirshberg isn't the first parent to become frustrated by the lack of healthy fast-food options for his kids during a road trip. But as president of Stonyfield Farm yogurt company, Hirshberg was in a position to do something about it. Now, six years after that fateful vacation in northern California, Hirshberg is overseeing a project he hopes will spark a revolution in the fast-food industry. It's called O'Naturals, a small chain of fast-food restaurants in the Northeast that offers everything from carrot ginger soup and organic smoked tofu to bison meatloaf sandwiches, and macaroni and cheese, much of it made with organic or natural ingredients.
